AR15 14.5-Inch 5.56 NATO Mid-Length Barrel, Government Profile
This 14.5-inch AR-15 barrel is chambered in 5.56 NATO and runs a mid-length gas system, spreading dwell time over a longer travel path to reduce mechanical wear on internal components. The 1:7 twist rate handles a broad range of 5.56 NATO and compatible loads, making it a practical choice for a duty-style or competition upper. The government profile and 1/2x28 thread pattern accept common muzzle devices built for that thread spec. Proudly Made in the USA.
Before assembly, confirm your gas block, handguard, and barrel nut are matched to the mid-length configuration. A mid-length gas tube is required for correct dwell timing, and you should verify clearance with your chosen upper receiver and bolt carrier group.
